Iterable over raw text documents expected, string object received
提问by thegreatcoder
I am currently trying to build a naive Bayes classifier as mentioned in this link.Referring to the line
我目前正在尝试构建一个本链接中提到的朴素贝叶斯分类器。参考线
X_new_tfidf = tfidf_transformer.transform(X_new_counts)
under the Training the Classifiersubheading, I had a similar line, X_new_counts = count_vect.transform(input.plot_movie)in my code which should take an iterable as an input to the transform function. The inputis a record from a DataFrame and is of type pd.Seriesand contains the following entries, out of which I send input.plot_movieas the input to the transform function:
在Training the Classifier副标题下，X_new_counts = count_vect.transform(input.plot_movie)我的代码中有一条类似的行，它应该将一个可迭代对象作为转换函数的输入。这 input是来自 DataFrame 的记录，属于类型pd.Series并包含以下条目，我将其中的条目input.plot_movie作为输入发送到转换函数：
However, I get the following error: Iterable over raw text documents expected, string object received
但是，我收到以下错误： Iterable over raw text documents expected, string object received
How do I fix this error? I also referred to thisanswer where the person says that sis an iterable because it was assigned a string. I also came across this linkwhere a TypeError: 'String' object is not iterableis encountered. Am I missing something here? The links seem to contradict each other.
我该如何解决这个错误？我还提到了这个答案，其中有人说这s是一个可迭代的，因为它被分配了一个字符串。我还遇到了遇到a 的链接TypeError: 'String' object is not iterable。我在这里错过了什么吗？这些链接似乎相互矛盾。
EDIT:I just realized that input.plot_movieis of type unicode and decided to convert it to a string. I encounter the same error again.
编辑：我刚刚意识到这input.plot_movie是 unicode 类型并决定将其转换为字符串。我再次遇到同样的错误。
回答by thegreatcoder
The solution to this problem is because input is just a String, but what is needed is a list (or an iterable) containing a single element (which is nothing but the String itself).
这个问题的解决方案是因为输入只是一个字符串，但需要的是一个包含单个元素（它只是字符串本身）的列表（或一个可迭代对象）。
The error can be removed by adding the following line:
可以通过添加以下行来消除错误：
input=[input]
before
前
X_new_counts = count_vect.transform(input.plot_movie)
